Abstract (en)

[origin: EP2012148A1] Decoration of a material is enabled with a high degree of recycling properties while satisfying the requirements for putting a structural color into practical use on the industrial scale. Furthermore, whether an object is genuine or not can be verified easily, and reusing by peeling as in the case of a hologram seal is prevented. A cavity 12 having a periodic structure 13 causing optical diffraction is formed in the inside of a substrate 11, and a periodic structure 15 causing optical diffraction is formed on part or the whole of the substrate 11. These cavity interface periodic structure 13 and the substrate surface periodic structure 15 have a regular arrangement developing a structural color. In addition, by bringing a functional material to be in contact with the substrate surface periodic structure 15, development of a structural color by the substrate surface periodic structure 15 is suppressed, thereby enabling a structural color developed by the cavity interface periodic structure 13 to be read.
